Diamond Fizz

1. In a cocktail shaker, combine the gin, lemon juice, simple syrup, and egg white.
2. Add a handful of ice cubes to the shaker and close it tightly.
3. Shake vigorously for about 15-20 seconds to ensure the ingredients are well mixed and the egg white is frothy.
4. Fill a highball glass halfway with ice cubes.
5. Strain the cocktail mixture from the shaker into the glass, using a cocktail strainer to catch any ice or foam.
6. Top off the glass with club soda, leaving a little space at the top for garnish.
7. Stir gently with a bar spoon to combine the ingredients.
8. Take a lemon twist and gently squeeze it over the glass to release its oils, then drop it into the drink.
9. Serve the Diamond Fizz immediately and enjoy!

Note: You can adjust the sweetness of the cocktail by adding more or less simple syrup according to your taste preference.
